Ohio Tax and Title Calculator: County Rates, Trade-Ins, EV Fees

To estimate your out-the-door cost with an Ohio tax and title calculator, you need four numbers: the vehicle’s price, your county’s combined sales tax rate (6.50% to 8.00%), the title fee ($18 or $23), and the base registration fee ($36 for a passenger car) plus any local permissive taxes. Whether the car is new or used and whether you’re trading something in changes the math significantly. Here’s how each piece works so you can run the numbers before you get to the counter.

Your County Sets the Sales Tax Rate

Ohio’s statewide sales tax is 5.75% under Ohio Revised Code 5739.02.¹ Every county adds a local and transit authority piece on top, ranging from 0.75% to 2.25%. That puts most combined rates between 6.50% and 8.00%.² Cuyahoga and Franklin counties sit at the top of the range at 8.00%.

The rate that applies is based on where you live, not where you buy. Drive from a 7.25% county to a dealership in a 6.75% county and you still owe 7.25%.³ Look up your county’s current rate on the Ohio Department of Taxation website before you plug anything into a calculator.

Trade-Ins Only Reduce Tax on New Vehicles

This is the rule that catches most buyers off guard. If you’re buying a new vehicle from a dealer and trading in your current car, the trade-in value comes off the purchase price before sales tax is figured. A $35,000 new car with a $10,000 trade-in is taxed on $25,000.⁴

Buy a used vehicle from a dealer and that credit disappears. You owe sales tax on the full purchase price, whatever your trade-in is worth.⁴ On a $20,000 used car with a $7,000 trade-in in a 7.25% county, that’s $1,450 in tax rather than the $942.50 the trade-in would have saved you on a new car.

Private-party swaps work the same way. If you and someone else trade cars with no cash changing hands, each of you owes tax on the fair market value of the vehicle you received.³

Title Fee

Ohio’s certificate of title fee is $18 in most counties, but a county board of commissioners can raise it to $23 by resolution, and many have.⁵ Financing the vehicle? The lien notation is bundled into that same fee as long as it’s filed with the title application. Confirm the local amount with your county clerk of courts.

Registration and Local Permissive Taxes

The base registration fee for a passenger car is $36.00.⁶ Counties, municipalities, and townships can each layer local permissive registration taxes in $5 increments on top. No single district collects more than $30 per vehicle per year, and no more than six $5 levies can be active in a given area at once.⁷ So annual registration on a passenger car runs somewhere between $36 and $66 depending on where you live.

Electric and Hybrid Surcharges

If you’re registering an alternative fuel vehicle, Ohio adds an annual surcharge to make up for the gas tax you’re not paying at the pump. Battery electric vehicles carry a $200 surcharge, and plug-in hybrids pay $150. Standard hybrids also face an additional fee, though lawmakers have proposed eliminating that one. Check the current amounts with the BMV before finalizing your budget, since legislative changes can take effect mid-year.

Dealer Documentation Fee

Dealerships charge a documentation fee (often just called a “doc fee”) to cover the paperwork they process for title, tax, and registration. It’s not a government charge; it’s dealer revenue. Ohio caps this fee under a formula tied to the Consumer Price Index, adjusted each October by the Registrar of Motor Vehicles.⁸ For 2026 the cap is approximately $398. It also cannot exceed 10% of what you owe before tax, title, and registration, which effectively lowers the cap on inexpensive vehicles. Private-party purchases don’t involve a doc fee.

Transfers That Owe No Sales Tax

Not every title transfer triggers tax. Ohio exempts transfers where no money or other consideration changes hands:

Gifts between parents and children or between spouses with no payment of any kind.
Gifts between unrelated people, as long as genuinely no consideration is exchanged.
Vehicles transferred through probate to a beneficiary, including a surviving spouse.
Court-ordered transfers from divorce, dissolution, or estate orders that don’t require the new owner to pay anything. If the order requires any payment — including debt cancellation — the transfer is taxable on that amount.

The controlling word is “consideration.” The moment anything of value changes hands (cash, forgiven debt, services, stock), the transfer becomes taxable.³ The title fee still applies even on an exempt transfer.

Sample Calculations

Say you live in Franklin County (8.00% combined rate) and you’re buying a new car from a dealer for $30,000 with an $8,000 trade-in:

Taxable amount: $30,000 − $8,000 = $22,000
Sales tax: $22,000 × 8.00% = $1,760
Title fee: $23 (Franklin County adopted the higher fee)
Registration: $36 base + $20 in local permissive taxes (example) = $56
Dealer doc fee: up to $398
Estimated total beyond the vehicle price: roughly $2,237

Run the same scenario as a used vehicle and the trade-in credit vanishes. Sales tax is now $30,000 × 8.00% = $2,400, and the estimated total climbs to about $2,877. That $640 gap is entirely Ohio’s new-versus-used trade-in rule.⁴ Add $200 to either scenario if you’re registering an EV.

Where and When to Pay

Sales tax and title fees are paid at the Clerk of Courts Title Office in your county, not at the BMV. You have 30 calendar days from the date of sale to complete the title transfer.⁹ Miss the window and a $5 late fee gets added to what you already owe. Call the clerk’s office ahead of your visit to confirm accepted payment methods, since some offices tack on a convenience fee for credit cards.

Registration and plates are handled separately at a BMV deputy registrar. In many Ohio counties the clerk of courts and the BMV share a building, so both errands often fit into one trip.

Extra Steps for Private-Party Buyers

Buying from a private seller means you carry the paperwork to the clerk of courts yourself: signed title, bill of sale or odometer disclosure, and payment for sales tax and the title fee. A dealer handles this for you. In a private sale, you handle it all.

Report the purchase price accurately. The Ohio Department of Taxation audits casual sales, and if the reported price looks unusually low, you’ll get a letter demanding proof of what you actually paid. You have 20 days to respond with documentation such as a notarized statement, a canceled check, or a bill of sale. Misrepresenting the price is a criminal offense that can carry up to six months in jail and a $1,000 fine.³
